Q

HCO3 base

A

Greater than 26 mEq/L

18
Q

The perfect PH balance

A

7.40

19
Q

How do the lungs compensate for acidosis

A

RR& depth will increase and CO2 will be blown off

H ions will be excreted and HCO3 will be retained

20
Q

How do the lungs compensate for alkalosis

A

RR & depth will decrease
CO2 will be retained

H ions will be retained and HCO3- will be excreted

21
Q

What regulates CO2(acid) levels within minutes

A

The lungs

22
Q

What regulate HCO3- (base) levels?

A

Kidneys
Slower system takes hours to days
